To all 'l 'ltom it may concern.

Be it known that l, JonN 1V. lmnurs, citizen ol the United States.residing at Silver City, in the county of Lyon and State of .\evada,have invented new and useful Improvements in Centrifugal Separators, ofwhich the following .is a specilieation.

My invention relaties to centrifugal separators, and pertains especiallyto separators of the type employing an outside rotary the blades ofwhich conveyer have a differential rotary motion to discharge the solidsat the lower end of the apparatus separate from the liquid which isdischarged at the topi The object of this invention is to devise asatisfactor means by which a minimum amount or agitation of the liquidundergoing separation will take place, so that the finer impalpableparticles of solid matter or solid matters which have apparently nomeasurable dimensions will be separated and collected. a

The invention consists of the parts and the construction and combinationof parts as hereinafter more fully described and claimed, havingreference to the accompanying drawings, in which- Figure 1 is a verticalsection, partly in elevation, of the invention. zontal section on theline. IZ-IU of Fig. 1.

In this improved machine I employ a sh ll made in two parts or sections.\2, each section being essentially in the form of a truncated cone,with the upper larger end of the lower section A extended in cylindricalform, as shown at 3, and'the abutting ends of the shell sections beingsuitably connected together, as shown at 1. The shell is open at bothtop and bottom and is supported ona vertical shaft 5, which latter ismounted in suitable bearings in the main frame of the apparatus.

A collar 7 is keyed to the shaft and carries an inclined detiectinganddistribut nc; disk 8 which is arranged proximate to the waist or widerportion of the interior of the shell.

The disk 8 does not extend to the shell, there being an annular spaceleft between the disk and shell, around and through Which all of theliquid and matter to be acted on passes. The disk 8 constitutes thefloor of the receivin hopper, and should not be perforate The uppersurface of the disk car- Fig. 2 is a horition of these vanes it is toforce all the material, both solids and liquids, heavy and light.through the space, around disk 8 into theqrreatest diameter of themachine and through the area of greatest separatingforce. These webs orvanes act similarly U) the 'anes of a centrifugal pump, and force theatlluent material through the stationary V 1 wall of water and solids inSllfilltllfiltill which conoulal shell and an inside spiral conveyei,

is formed at 1) above and below disk 8, when the machine is running.

()n the under side of the disk 8 is a downwardly extending, peripheral,cylindrical tlange til which is parallel with, and spaced from. thecylint'lrical section 3 of the shell, and with the interior of thisflange coincident with. and in fact, locating the waterline D. Theallluent. material which is fed in through the hopper is forced by theaction of the vanes 11 outward and over the edge of the plate 8 and downthrough the annular space between the parts 13--3 and driven throughthis imaginary barrier D,

and all material subjected to the greatest;

All liquid before itcan be discharged from the machine must pass firstthrough the area of greatest separating force in the machine, and thenstrain back to the outlets 12 against centrifugal force. In doing so theliquids are thereby separated from the solids, which latter are thrownagainst the casino 2 and removed by the spiral scrapers 15. These spiralblades or scrapers 15 are fixed to the radially disposed webs 16, which,latter are "carried by a hub 17 secured" to a sleeve or hollow shaft 18rotatable on suit able bearings 19 about, and concentric with, the shaft5; the two shafts 5 and 18 having motion in the same direction, but at.slightly ditterent rates of speed.

Tothe top of the supporting Webs 16 is fixed a ring 20 suitably spacedfrom the-disk 8 above. the disk 8 and ring 20 inelosing a space whichopens outward to the shell for the reception of the separated liquid.The

ring 20 prevents the liquid which passes be ries a number of radial webs0r vanes 11 1 low it from rushing upward and out through e pipes 12; thewater below the i .1 i usual; being more or less muddy, owing to he 0 4erstion of the blKlES.

constitutes the main features of this present invention. As the shellcontracts toward the lower end, the pitch of the blades 1-5 increases'so as to compensate for the greclusolids along the space insidethe Water-line,

thereby drying the solids before discharging them,
